Windows下使用UIAutomation技术遍历桌面窗口和指定窗口内容的AutomationWalker.exe的C#源代码

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading;using System.Threading.Tasks;using System.Windows.Automation;//引用\"C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.6.1\\UIAutomationClient.dll\"//引用\"C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\.NETFramework\\v4.6.1\\UIAutomationTypes.dll\"namespace ConsoleApp1{ class Program { static void WalkElement(AutomationElement element, TreeWalker walker, int depth, int limit) { Console.WriteLine($\"{new string(\' \', depth * 2)}\" + $\"\\\"{element.Current.Name}\\\"\"); if (limit>0 && depth>=limit) return; AutomationElement child = walker.GetFirstChild(element); while (child != null) { WalkElement(child, walker, depth + 1, limit); child = walker.GetNextSibling(child); } } static void Main(string[] args) { if (args.Length < 1) { Console.WriteLine(\"Usage: AutomationWalker \\\"window_title\\\"|desktop\"); return; } else if (args[0]==\"desktop\") { try {  Console.WriteLine(\"Walker desktop begin ...\");  //Get the destkop element  AutomationElement elemDesktop = AutomationElement.RootElement;  TreeWalker walker = TreeWalker.ControlViewWalker;  WalkElement(elemDesktop, walker, 0, 1);  Console.WriteLine(\"... Walker desktop end.\"); } catch (Exception) {  Console.WriteLine(\"Walker desktop error!\"); } return; } try { Console.WriteLine(\"Walker begin ...\"); //Get the destkop element AutomationElement elemDesktop = AutomationElement.RootElement; //Search the Application main window by title from all children PropertyCondition pCondition = new PropertyCondition(AutomationElement.NameProperty, args[0]); AutomationElementCollection elemApplicationWindows = elemDesktop.FindAll(TreeScope.Children, pCondition); Console.WriteLine(\"elemApplicationWindows.Count:\" + elemApplicationWindows.Count); for (int i = 0; i < elemApplicationWindows.Count; i++) {  TreeWalker walker = TreeWalker.ControlViewWalker;  WalkElement(elemApplicationWindows[i], walker, 0, 0); } Console.WriteLine(\"... Walker end.\"); } catch (Exception) { Console.WriteLine(\"Walker error!\"); } } }}

将以上代码放在C#控制台项目中，生成AutomationWalker.exe

用法：

在cmd窗口中输入命令

AutomationWalker.exe desktop

列出当前桌面上所有窗口的用双引号括住的标题，比如

Walker desktop begin ...
\"\"
  \"\"
  \"管理员: 命令提示符 - automationwalker  desktop\"
  \"新标签页 - Google Chrome\"
  \"dummyLayeredWnd\"
  \"Program Manager\"
... Walker desktop end.

输入命令
 

AutomationWalker.exe \"新标签页 - Google Chrome\"

列出窗口\"新标签页 - Google Chrome\"的内容。

当你想要提取某个窗口的文本内容时，使用AutomationWalker会很方便。
